Neurogenic tumors of the mediastinum may have an intraspinal component connected by a narrowed segment of tumor of in the intervertebral foramen, then have symptoms of back pain, lower extremity tingling sensation. CT scan or MRI demonstrated a
Dumbbell-shaped mass density compressing spinal canal, enlargement of the foramen, erosion of bone, and intervertebral widening.
We report the analysis of the 18 cases of neurogenic tumors on posterior mediastinum and Dumbbell type tumors are 3 cases among the 18 cases. The neurilemmomas were 12 cases(67%), the ganglioneuroma were 5 cases(28%), and neuroblastoma was one
case(5%).
The successful removal was done in all cases, a standard thoracotomy and laminectomy was done in Dumbbell type tumors. There was no postoperative neurological complications. (Korean J Thoracic Cardiovas Surg 1994; 27:938-41)
